Phylogenetic relationships within sample of phylogenetic tree vertebrates liolaemid lizard genus Phymaturus were studied using parsimony analysis of morphological data. The data set includes characters: 28 described in the literature as apomorphies of the three genera of Liolaemidae Ctenoblepharys, Liolaemus, and Phymaturus21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals of Phymaturus, and 31 from the skeletal anatomy.

This data set includes representatives of 10 of the 12 species currently recognized in the literature plus twelve other terminals considered in this study and representing independent lineages assigned to patagonicus or palluma. Four of these terminals are described in the present study as new species, one belonging to the palluma group and the other three to the patagonicus group.

We performed define the composition of atmosphere analyses using different methods of coding binary polymorphic characters, and a new method for treating continuous characters. The traditional division of the genus in two groups is not supported here, with the patagonicus group resulting paraphyletic in some of the analyses.

The palluma group is monophyletic and supported by many characters. A majority rule consensus tree of all runs recovers a reasonably well-resolved topology of the group. All analyses recovered a northern subclade within the palluma group, formed by species distributed in Argentina from northern of San Juan province north to 30 degrees of latitude. In this analysis palluma from El Planchón Chile was found sample of phylogenetic tree vertebrates be more closely related to this northern subclade than any other "palluma" form.

Bolivia The data set includes characters: 28 described in the literature as apomorphies of the three genera of Liolaemidae Ctenoblepharys, Liolaemusand Phymaturus21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals sample of phylogenetic tree vertebrates Phymaturusand 31 from the skeletal anatomy.

In this analysis palluma from El Planchón Chile was found to be more closely related to this northern subclade than any other " palluma " form. Phymaturus comprises a group of iguanian lizards inhabiting rocky places of Patagonia and both eastern and western mid- to high-elevation slopes of the Andes. This group of viviparous and herbivorous lizards reaches its northern limit in the Puna region of Catamarca in northern Argentina.

According to Etheridge species of this clade of iguanians are characterized by having wide and flattened head and body, tail with a regular whorls of spinose scales, lateral nuchal skin folds with fat-filled pouches, a short interclaviculae, among other characters that are exclusive and provide strong evidence of monophyly. At the time of Donoso Barros and Peters and Donoso Barrosthe genus included only one species with two subspecies: palluma palluma Molinaand palluma patagonicus Koslowsky Much of Pereyra's a information was included and reevaluated sample of phylogenetic tree vertebrates the present study.

Etheridge provided the first extensive study of genera now included in the Liolaemidae Phymaturus, Liolaemus, and Ctenoblepharysand proposed a cladistic taxonomy based on morphological characters. Within Phymaturus Etheridge recognized two groups of species, the palluma group with four species, and the patagonicus sample of phylogenetic tree vertebrates formed by six species formerly considered subspecies of patagonicus by Cei [].

Characters defining the palluma group were the non-imbricate superciliaries, five or more suboculars, three to four rows of lorilabials, mental narrower than rostral and usually in contact with sublabials, caudal spines well developed, and two annuli per segment. For the patagonicus group, Etheridge identified a splenial short and a fused Meckel's groove.

However, Etheridge noted that these groups may not necessarily be monophyletic. Following this work, no additional studies were published that sought to recover the genealogical relationships within the genus, yet, many questions remain, like the validity and or monophyly of Etheridge's groups of species, and the phylogenetic relationships among species.

The latter issue remains a problem that needs to be resolved through the examination of populations on both sides sample of phylogenetic tree vertebrates the Andes, and compared to the type material deposited at the British Museum of Natural History. The goal of this study is to provide a first comprehensive analysis of Phymaturus, using cladistic methods. We studied the external morphology and skeletons of an extensive sample of terminals and individuals. We examined and described more than informative characters, most of them used in does linkedin tell you when you remove a connection systematics of Sample of phylogenetic tree vertebrates for the first time, as well as other characters taken from the literature.

For the phylogenetic analysis we were able to reexamine the type series of nine of the 12 currently recognized species with the exception of palluma, verdugo, and calcogaster. Characters used in this study were obtained primarily from the skeleton, squamation, morphometry, and body patterns. The allozyme data set plus two chromosomal characters of Pereyra a were also included. Skeletal characters were visualized from cleared and stained material following Wassersug's technique, which allows differential staining of cartilage and bone.

For some specimens MVZ and SDSU dry skeletons however, cartilaginous structures larynx, trachea, why my phone doesnt connect to tv hyoid apparatus were not available because they were prepared as dry skeletons. Characters for phylogenetic analysis were scored only from adults.

Ontogenetic shift in external sample of phylogenetic tree vertebrates between juveniles and adults was recorded and it is presented in a separated section. Museum numbers and localities for specimens included in this study are listed in Appendix I. For a details and a list of characters see Appendix II. He found characters discriminating payunae and cf.

Also we included his data set of allozymes 19 characters and two from karyology diploid chromosomal number and number of microchromosomes in femaleswhich were available for four of our terminals P. We added diploid chromosomal number to two other terminals, P. We choose TNT for our analysis because this is the only program that allows the analysis of continuous characters without first converting them in discrete characters as proposed by Thiele, Data matrices are available at www.

There is more than one matrix because different coding methods were applied for binary polymorphic characters. The first block in matrix is comprised of continuous characters 26 for external morphology and 14 for skeletal anatomythe same characters are included in the following block characters ; ; During searches we deactivate these characters if we use the range method for continuous, and the opposite to apply Thiele's gap-weighting method Thiele, For TNT numeration of characters begins with the first block with character "0" designating the first oneso the second block traditional format starts with character The list of characters in text are equivalent in TNT format of our matrices to Sample of phylogenetic tree vertebrates our analysis we considered the following TNT characters non-additive allozyme characters: ; and throat pattern of males and females, dorsal pattern of tails:and and"smooth pattern" and dorsal pattern black with two sample of phylogenetic tree vertebrates of occelli ; all remaining characters were additive.

Binary polymorphic characters were analyzed in four different ways: any-instance the polymorphic species is considered already having the novelty, so it is coded "1" as in species that this state is fixedscaled polymorphic species have an intermediate state "1" in an ordered series between species not having that derived state "0" and those having the derived state "2"frequency bins frequency of the presence of the derived state is used to score each species, percentage ranges are divided by 09 states for TNT analysisand missing question mark for polymorphic species.

For more details on these methods and performance of them in cladistic analysis see Wiens TNT uses Farris'optimization Farris, to estimate distances and costs among ranges, when ranges between two terminals overlap, TNT assumes zero cost. In this way the costs of the continous characters are similar to the others. For frequency bins we preferred not dividing by more states than 10 because the limited sample size we had of some species.

For rooting our trees we included the other two liolaemid genera, Liolaemus three species: L. Recent DNA analyses support a Phymaturus-Liolaemus sister-taxon relationship with Ctenoblepharys adspersa as the basal member of the family Schulte et al. In addition to these species, we included twelve populations that are assigned to named species yet show morphological evidence of evolutionary isolation likely representing independent lineages from nominal forms.

Four of these terminals are described below as new species. Espinoza, unpubl. Of the twelve terminals added to this analysis to the currently recognized species, four exhibit obvious discriminating characters squamation and patterns that justitfy their description as new species.

Diagnosis: Phymaturus dorsimaculatus belongs to the palluma group sensu Etheridge, because it has square-shaped non-imbricate superciliaries, rugose dorsal scales of the tail, usually a fragmented subocular, and the subocular-supralabials separation is two or more scale rows. It is distinguishable from all other species in the group by its unusual dorsal pattern. Dorsal pattern from occiput to the posterior region of trunk with black transverse bands interrupted medially Figure 1A.

Adults of cf. Phymaturus dorsimaculatus never have a divided rostral scale as does many punae, antofagastensiscf. Most specimens from northern Argentina of the palluma group exhibit a homogeneous and dense "spray" pattern on their dorsum Figure 12C and lack black reticulation or spots.
